FF v133.0 when maximized causes Windows taskbar to not appear when moving the mouse to the bottom of the screen

more options

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

What OS?

Apologies. I thought when I put it in the input box where it says it detects my OS that it'd show in the post.

I'm on Win 10 Home 22H2

Thank you.

Tried the xulstore.json reset/rename

No change in behavior.

Only workaround that currently works is pressing the Windows key or taking Firefox out of maximize and re-maximizing. Without doing either of these things, Windows taskbar cannot be accessed. It's admittedly minor but is a bit annoying

Yeah, Windows 11 taskbar is very annoying not being able to change the size of it. I'm rarely in windows anymore.

I'd be more willing to place the blame on Windows here since it often is to blame but Firefox seems to be the only application that has this issue
